Repairing Copiers & Faxes/Canon PC740 copier

QuestionCould anyone advise please how i remove the glass on the platten so i can attend to a problem with the light mechanism? what has happened is the drive cord appears to have come off the pulleys
many thanks

AnswerI cannot answer this question as this presents a liability issue... if the glass for some reason were to break and you were to cut yourself... I would be liable for this... I can advise you on the drive mechanism... if the drive cord has come loose... it means that the drive cord has worn out... it will fall off again... it needs replacing... I recommend contacting some repair shops on estimates for replacing it... parts and labor...
